π§ͺ GitHub PR Agent β Native GitHub Automation
The GitHub PR Agent runs automatically in GitHub Actions when a pull request is opened or updated.
It detects changed code, analyzes coverage, generates targeted unit tests, and commits them back to the PR branch β all with zero manual effort.
π When to Useβ
Use the GitHub PR Agent when:
- You're using GitHub Actions
- You want fully automated test generation per pull request
- Your team prefers a zero-config, GitHub-native workflow
